Caryocar nuciferum which is cultivated in Dutch and French Guiana, and which, with the almendron of Mariquita (Caryocar amygdaliferum), the juvia of the Esmeralda (Bertholletia excelsa), and the Geoffroea of the Amazon, yields the finest almonds of all South America.

* According to the report of several Indians, only the smaller rodentia, particularly the cavies (the acuri and the lapa), by the structure of their teeth, and the inconceivable perseverance with which they pursue their destructive operations, succeed in perforating the fruit of the juvia.
